2. Combustion of fuels with air at high temperatures can produce nitrogen/oxygen compounds (NOx) as unwanted by products. Because these compounds are pollutants, they must be removed, and one process for doing so is called selective catalytic reduction (SCR). A researcher claims to have developed a new SCR catalyst that uses ammonia (NH3) as a reactant to convert NO into nitrogen and water via the reaction: 6NO(g) + 4NH3(g) ---> 5N₂(g) + 6H₂O(g) We are working on the design for a process using this reaction in which 120 mol/hr of an equimolar mixture of NO and NH3 (i.e., 60 mol/hr NO and 60 mol/hr NH3) at 450°C is fed to the reactor. We may assume that the reaction goes to completion in the limiting reactant. The reactor is jacketed to maintain the temperature at 450°C, and we may assume that the pressure is held constant at 1 Atm. Use the following constant heat capacities for the gases: (a) (b) I (c) [ Species NO (g) NH3(g) N₂ (g) H₂O (g) Cp (J/mol K) 30.5 37.0 29.1 34.2 Determine…
